My invention is concerned with controlling support 17. In its preferredconstruction, valves for pumps operated by compressed air thecylindrical casing 19 is provided with the or other gases and employedin the elevation annular flanges 21 at its ends, which flanges of wateror any desired liquid from wells, are connected by the screws 22 withthe ends mines, etc, and is designed to produce a de- 23 which havebearings for the shaft 24, which 55 vice of extreme simplicity whichwill be camay be integral with the valve 25, if desired; pab-le ofoperating successfully under a wide On one end of the shaft 24 issecured the variation in the air pressure employed and sprocketwheel 26or whatever other gearing in the height to which the liquid is elevated.is employed to connect the valve with the mo- To illustrate myinvention, I annex heretor 16, the sprocket chain 27 and sprocket 60 totwo sheets of drawings in which the same pinion 28 being preferablyemployed for this reference characters are used to designate purpose.

Their communication is shut pressed air tank 11 of suflicientcapacity so off by the unchanneled portion of the pethat any ordinaryamount of water can be riphery, and coinciding with the unchan- 5 liftedfor domestic purposes or otherwise, neled portionI provide the exhaustpassages and I connect this compressed air tankll by 41, preferablysegmental in their outline and i a pipe 12 having a shut-off cook 13therein opening into the central exhaust port 42 to an air compressor14, which may bedriven which opens to the atmosphere, as will be by anyavailable power, such as a windmill, readily apparent. The ports 31 areconnected to electric motor, gas engine, etc, and this air with theseexhaust passages 41 by the ports 43 compressor is connected by suitablegearing which are formed in the base 20 and terminate such as sprocketwheels and chain 15 with in the vertical planes of the exhaust passagesa motor 16, which is preferably located at 41. It will of coursebeunderstood that the some suitable point relative to the openingpassages 41 and the channels 30 are diat5 of the well. I haveillustrated diagrammatmetrically opposed to each other so that thereically a support 17 as located over the top of is always a supply ofcompresed air flowing the well and carrying the valve 18, which as intothe well so as to discharge the water seen in Figs. 3 and 4 consists ofthe cylindritherefrom in a continuous stream where the cal casing19mounted upon the supporting duplex arrangement shown is employed.

is base 20, which in turn will be carried by the 11e pipes 32 are passedthrong the closed 1 0 tops of the air chambers 44, which are located inthe well in such a position that the water normally stands substantiallyas high as their tops. The bottom of these chambers will be providedwith some form of valve which automatically opens to admit the water tothe bottom of the chamber when there is no air pressure on the chamber,and which will close when air pressure is applied. To carry out thewater, I employ'in each chamber a water discharge pipe 45, which willextend to near the bottom of the chamber and be provided with anupwardly openingcheck valve. In a duplex system, these pipes preferablyopen into the common horizontal connection or header 46 by the elbow 47and the T 48, and this header 46 is connected by the elbow 49 with thewater delivery pipe 50 which of course extends to the top of the wellfrom which point it can be led off to any desired place, whether to ahouse to furnish water supply, or for fire protection, or to a field forirrigation or to whatever place the water is used.

The general operation of the system will be readily aparent: Assumingthat the tank 11 is full of-compressed air, then if the valve 25 isturned by hand or by the motor so as to bring the channel or channels 30into connection with the compressed air supply, the "pressure will passdownward through the pipes 32 and forcethe water trapped in the airchamber 44 up through the pipe 50. If the valve 25 is operated by hand,and it is desired to-deliver less than the capacity of the chamber 44the valve will be turned backas soon asthe desired quantity of watcrislifted so asto bring the unchanneled portion of the valve into registerwith the ports31 and 40, and whenthis occurs, the pipe 32 is connectedwith the exhaust, and the compressed air in the chamber 44 isallowed toescape and the water will rise in the chamber and fill the same. Wherein a-duplex system the valve is driven by themotorcontinuously, thepumpin is constant, as the pressure ofthe air relative to thesize of thechamber and the rapidity with which the water can enter will beregulated so thatone chamber will be filled with the water while thecompressed air is exhausting therefrom and the other chamher will at thesame time be emptied of water. Where a well'of a smaller bore is to havethe water elevated therefrom, I preferably employ the construction shownin Fig. 2,

where 'it will be seen that the lower end of the casing section '51 isclosed by the novel construction therein shown, which consists of asleeve-52 having-the valve seat '53'on its interior and having itslarger top connected with the smaller bottom portion 54 by aninclinedportion 55 which is adaptedto co-operate with the compressibleand elastic packing 56, which is-supported lnfiIlCl'SBCUleCl tothepacking ring 57. The interior of the ring 57 as well as the exterior ofthe reduced portion 54 are threaded and both the sleeve and the ring areprovided with recesses 58 or some suitable means by which wrenches canbe applied so that the device can be secured airt ght and firmly inplace near the end of the casing section simply by screwing the twoparts together, thereby compressing the packing 56 against the innerwall of the casing with suflicient force tohold it in place against theair pressure applied thereto. Co-operating with the valve seat 58 is theupwardly opening valve disk 59, which is preferably provided with thedownwardly extending stem 60, to which is connected the hollow metallicfloat 61 which tends to keep the valve open, its upward movement beinglimited by the rod 62 secured across the top of the sleeve for thispurpose. If the water is of a character that needs straining, for thisrod 62 I may substitute any desired form of a screen which will thushave the double function of straining the water and holding the valve inplace. At a suitable distance above, preferably in the bottom of anadjacent section 51 of the casing, I secure the somewhat similar plug63, which corresponds to the sleeve 52 except that it is solid, and hasthe pipe 45 passed therethrough and the pipe section can be threadedtherethrough as shown, or secured in place by collars co-operatingtherewith and with the plug 63. The end of the pipe 32 will likewise bethreaded into the plug 63, and after said plug is secured in place bythe same means as the plug in the bottom section of the casing, theadjacent ends of the casings can be united by the coupling ring 64 in amanner well understood. To furnish a check valve for the bottom of thepipe 45 I preferably employ a small union 65 having the valve seat 66and the stop pin 67 therein and adapted to receive the poppet valve 68,which will operate in a manner readily understood. It will be notedthatI have formed in the valve body 25 the three or more annular rectangulargrooves 69 in which I have placed the expanding piston rings 70 so asto prevent leakage between the difierent portions of the valve. Ofcourse it will be understood that I might substitute some other form ofpacking for these piston rings 7 O.

lVhileI have shown and described my invention as embodied in the formwhich I at present consider best adapted to carry out its purposes, itwill be understood it is capable of'modifications, and that I do notdesire to be limited in the interpretation of the following claimsexcept as may be necessitated by the state of the prior art.
